WASHINGTON — Vice President Joe Biden has had his fair share of criticism, but some may become more restrained to voice it after a Thursday revelation: He runs a fight club.

Even more shocking, the second-most powerful man in the country runs a fight club in the basement of the White House. Biden’s actions came to light after he left a copy of the official fight club rules in a copy machine.

“I don’t know what to say,” Biden told a reporter. “But I tell you what: Come down to the basement at 8 p.m. on Friday, and we’ll talk about it some more.”

According to an aide, Biden had only just recently saw the film “Fight Club,” based off of the popular Chuck Palahniuk book of the same name. The vice president was reportedly enthralled by both the idea of a fight club and the film’s twist ending, which he somehow hadn’t heard about by now.

“He just couldn’t believe Ed Norton and Brad Pitt were the same person,” the aide said. “He talked about it for days. Now he seems to be playing the role of two people himself — vice president and fight club combatant.”

The spot has become popular for Democrats and Republicans alike, according to Washington insiders. Notable members reportedly include Sens. Harry Reid, John Boehner and Eric Cantor. N.J. Governor Chris Christie is said to now have an interest after seeing the physical changes of officials partaking in the group.

President Barack Obama has stayed mum on the subject for now, citing “bigger things to worry about.” However, rumors persist that Obama sometimes walks down the stairs to enjoy a few rounds.
